(既然下雨了，我们就在家待着吧。) 一句话区分：说最重要的原因用 because，说大家都知道的背景用 since/as。 三、 核心规则与易错点 (必看) 规则 正确示例 错误示例 为什么？ 1. Because 和 So 不连用​ ✅ He was tired, so​ he went to bed early. ✅ He went to bed early because​ he was tired. ❌ Because​ he was tired, so​ he went to bed early. 英语中，because​ (从属连词) 和 so​ (并列连词) 功能重复，二者只能选一个。 2. Because 接句子，Because of 接“东西”​ ✅ I stayed home because I was sick. (接句子) ✅ I stayed home because of my sickness.

Inside was an old brass compass（指南针） and a handwritten note: "Some things find you when you're ready to look." Leo was puzzled（困惑的） at first. Why send a compass? He wasn't into hiking（徒步旅行） or orienteering（定向越野）. But that evening, he noticed something strange—the needle didn't always point north. Sometimes it twitched（微动） slightly when he spoke certain words aloud. Curious, Leo showed the compass to his science teacher, Ms Hu. She examined it carefully and said, "This might be an early 20th-century magnetic（磁的） variation model—quite rare. Your grandfather must have wanted you to discover its secret yourself." That weekend, Leo and his dad set up a small tent in the backyard. Using the compass, Leo learned to read directions. He realised his grandfather hadn't just given him an antique—he'd given him a reason to explore（探索） the world beyond his screen. 26. What was inside the parcel Leo received? A. A rare stamp and a letter. B. An old brass compass and a note. C. A tent and a camping guidebook. D. A science textbook from his grandfather. 27. Why was Leo confused when he first opened the parcel? A. He didn't know his grandfather's address. B. He had never been interested in compasses or hiking. C. The compass was broken and pointed nowhere. D. His grandfather had promised him a telescope instead. 28. What unusual thing did Leo notice about the compass? A. It glowed in the dark. B. Its needle sometimes twitched when he spoke certain words. C. It only worked outdoors. D. It played a melody when opened. 29. What did Ms Hu suggest about the compass? A. It was a common souvenir with no special value. B. It had been stolen from a museum. C. It was a rare magnetic variation model worth discovering. D. It needed new batteries to function properly. 30. What is the main idea of the passage? A. How to use a compass for orienteering. B. An unexpected gift can inspire curiosity and exploration. C. Grandfathers should always explain their presents. D. Old objects are more valuable than new ones. （二）首字母填空（共10小题，每小题1分） 根据短文内容和首字母提示写出所缺单词的正确形式。 【改编自 Chicken Soup for the Teenage Soul】 Last month, something u\_\_31\_\_ happened to me.
